Quality of Service (QoS): Managing Bandwidth More Effectively Using QoS Classifiers To Configure Quality of Service for Outbound Traffic Syntax: vlan < vid > qos priority < 0 - 7 > Configures an 802.1p priority for outbound packets belonging to the specified VLAN. This priority determines the packet's queue in the outbound port to which it is sent. If the packet leaves the switch on a tagged port, it carries the 802.1p priority with it to the next downstream device. You can configure one QoS classifier for each VLAN-ID. (Default: Nooverride) Syntax: no vlan < vid > qos Removes the specified VLAN-ID as a QoS classifier and resets the priority for that VLAN to No-override. Syntax: show qos vlan-priority Displays a listing of the QoS VLAN-ID classifiers currently in the running-config file, with their priority data. 1. For example, suppose that you have the following VLANs configured on the switch and want to prioritize them as shown: ProCurve(config)# show vlan Status and Counters - VLAN Information Maximum VLANs to support : 8 Primary VLAN : DEFAULT_VLAN 802.1Q VLAN ID 1 22 Name -----------DEFAULT_VLAN VLAN_22 Status -----------static static Figure 5-16. Example of a List of VLANs Available for QoS Prioritization 2. You would then execute the following commands to prioritize the VLANs by VID: 5-42
